Just days after laying into products that dare to be made by a company other than his beloved Apple, actor and comic Stephen Fry - possibly Britain's favourite person - has taken a verbal hatchet to Microsoft's Windows Vista and a Sony Vaio laptop via Twitter.

Twitter fan Fry explained that he needed a PC laptop to "review things" and went for a Sony Vaio laptop running Windows Vista.

It didn't take long for Fry to lose his patience.

"I hate Vista so much I want to cry. Bought a Vaio. The most useless $4k ever spent. It just will not join a sec-enabled network.

"I have nine Macs!!!!!! I don't need another **** Mac. I just want ONE ARSING PC that isn't complete ****.

"Too late. It's going out the window. I can't put up with this sort of arse.

"Listen, I have Parallels, I have Fusion, I have 2 distros of Linux. I need just one, just 1 of **** Vista so that I can review things.

"Forgive intemperate language, but every time I buy a PC they're worse, not better than they were before and it make me so angry I could kill."

Fry's sense of calm and decorum eventually returned: "I've calmed down now. Vista and PCs are so crap it's funny."

At the end of November, Fry used Twitter to call the BlackBerry Storm "shockingly bad" and "embarrassingly awful".

Blackadder and Bones star Fry, who insists he "SO wanted to like it", accuses the Storm of "terrible lag: inaccurate t'screen, awful, slow and fiddly text input.

"Plus the GPS maps won't work - issue with BIS connections. iPhone killer? Ha!"

Fry isn't blinkered about Apple. In September 2007 Fry slammed Apple's original iPhone for only supporting server-side applications, predicting that closed environments aren't the future for the technology industry.

"All the big guns want an iPhone killer. Even I, mad for all things Apple as I am, want an iPhone killer. I want smart digital devices to be as good as mankind's ingenuity can make them. I want us eternally to strive to improve and surprise. Bring on the iPhone killers. Bring them on," he writes.

Fry purchased the second Mac ever shipped into the UK, with the first being acquired by his friend, the late Hitchhiker's Guide author Douglas Adams.

Of the iPhone, Fry concluded: "Everything else in the iPhone lives up to, even surpasses the hype. Another triumph for Jonathan Ive and his design team, Apple has made a wholly desirable and beautiful object. Only a cross and silly person would pretend to be unimpressed or make claims of parity about their O2 XHA Trion or similar lumpen beast."
